CS45-B2GA101K-GKA Equivalent & Substitute Parts

Part Overview

The CS45-B2GA101K-GKA is a 100 pF ceramic capacitor rated for 440VAC operation, manufactured by TDK Corporation. This high-voltage radial disc capacitor is designed for safety-critical applications with X1, Y2 ratings and operates across a temperature range of -25°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CS45-B2GA101K-GKA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CS45-B2GA101K-NKA qualifies as a direct equivalent based on the following criteria:

• Identical capacitance value: 100 pF
• Identical tolerance: ±10%
• Identical voltage rating: 440VAC
• Identical temperature coefficient: B
• Identical operating temperature range: -25°C to 125°C
• Identical safety ratings: X1, Y2
• Identical mounting configuration: Through Hole, Radial Disc
• Identical lead spacing: 0.295" (7.50mm)
• Identical lead style: Formed Leads - Kinked
• Identical RoHS compliance: ROHS3 Compliant

Both parts belong to the TDK CS45 series and share identical physical dimensions (0.256" diameter) and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CS45-B2GA101K-GKA and CS45-B2GA101K-NKA are active production parts from TDK Corporation with full ROHS3 compliance. Selection between these parts should be based on availability and lead time requirements, as they are electrically and mechanically identical. The CS45-B2GA101K-NKA currently maintains higher inventory levels (1734 pcs vs. 677 pcs), which may provide supply chain advantages for high-volume applications. Both parts satisfy X1, Y2 safety ratings for use in safety-critical circuits and maintain identical performance across the specified operating temperature range.
